ASSIGNOB TO THE CLEVELAND WIRE ATIAOI-IIVIENT FOR SPRINGS.

Application filed September 14, 1908.

T 0 all whom it may concern:

Be it known that I, CHARLES R. BARKER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Attachments for Springs,and do declare that the follow ing is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention has reference to improvements in springs for beds andcouches and frames therefor, and the invention consists, first, in a newand original construction of spring as an article of manufacture andsale, and in a special construction of frame in which the spring isadapted to be engaged by rotating or turning it to its seat thereonthrough holes in said frame, all substantially as shown and describedlarly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of the springand a cross section of the frame, or a part thereof, on which the springis seated, and Fig. 2 is a view of said parts at right angles to Fig. 1.Fig. 3 is a perspective view of a section of the frame or rail providedwith a pair of engaging holes for the spring. Fig. t is an elevation ofthe spring alone, and Fig. is a plan view of a section of the rail andthe spring on line 5-5, Fig. 1.

As thus shown the parts consist in the spring S and the frame F in whichthe spring is removably seated. The said frame, so-called, is to beunderstood as constituting the support for the springs whether it be theouter portion of a bed or a couch frame on the inner cross bars, orslats, or both, it being understood that in any case the frame, bar, orslat is of the angle iron pattern and provided with holes 2 in pairs inangle 3 of said part F adapted to have the spiral wire S threadedthrough the same and turned therein to its seat, Figs. 1, 2 and Now, itwill be noticed that said spring is shown as a spirally wound memberlargest at its top or upper end on which rests the mattress andgradually reduced to its lower end or base where it engages rail orframe F. In these general features the spring is not new, but inaddition to these and as an original and novel feature I wind the smallend Specification of Letters Patent.

or apex of the spring with a plurality of coils or convolutions 4 of thesame cross section, substantially, and with spring tension one upon theother as tightly as can be, and the extremity or end 5 of the said coilis bent or deflected downward somewhat to facilitate engagement with theframe. The distinct novelty of the spring therefore is focused in thispeculiar and original construction of the smaller end thereof, whereby aconstruction is produced which makes a gripping or bending engagementwith the bars or the frame F without other means for making attachment.The said frame is constructed throughout its spring support ing portionwith angle bars of the shape shown whether of iron or steel, and to thisend both the side-bars and the cross-bars or rails of the frame alikeare of the said angle iron pattern. This style of bar affords a flat topseating surface 6 for the spring and a strengthening side or flangeportion 7, and the holes 2 are formed through angle 3 in pairs or groupsof two at all points where a spring is to be set. These holes are spacedapart in pairs to correspond with the arc of the coils of the wire orspring at i, so that when the extremity 5 is inserted in one hole 2 andthe spring is rotated by hand it will carry the said extremity around toand thread it into the other hole by simply continuing the rotation. Indoing this the coils l are forced open against their tension accordingto the thickness of the metal that comes between, and at last the end 5is car ried around to stop against the inner side of down flange 5 ofthe rail just below the hole it first entered, thus throwing practicallyone and a half of the said coils beneath the horizontal seating portion6 of the rail or frame and causing a very firm grip or hold to be takenupon both sides on said seating portion of the bar.

The operation of attaching the springs becomes easy and rapid after alittle practice, and a novice can soon learn to do the assembling. Thenwhen the other end of the springs are bound together in all directionsas usual to receive the mattress, the springs are prevented from turningloose from the rails and the bed bottom is completed.

The term angle-iron as used herein means any frame piece or part ofright angled form like that shown whether of iron,

steel or other metal and is to be so understood in the claims, andthough an entire bed frame is not shown, it will be understood that theentire frame is like the portions shown, the springs being interlockedtherewith and detachable for replacement if necessary.

What I claim is 1. In bed and couch bottoms, a right angled rail havingholes in pairs through the angles thereof, in combination with springsengaged through said holes and locked on said rail.

2. A couch or bed frame constructed of angle iron pieces with one sidearranged horizontally and provided with holes in pairs through theangles thereof, in combination with spirally wound springs having opencoils, and the coils at one end engaged through said holes and the saidsprings seated upon said horizontal sides of said pieces.

3. A bed or couch frame consisting of angle iron frame pieces havingholes in pairs through their angles and the sides of the said piecesarranged horizontally and verti cally, in combination with spirallywound springs having coils of substantially the same cross sectionthreaded through said holes and the lower coil of each spring having itsend resting against the vertical side of the frame piece carrying thesame.

in testimony whereof I sign this specification in the presence of twowitnesses.
